Measurement of Diameter of Spinal Canal in Nepalese Population

Abstract

Introduction: A typical vertebra has a ventral body, vertebral arch, and a vertebral foramen, where the spinal cord, meninges, and related vessels occupy. Depending on the position and amount of narrowing that occurs over time, a spinal nerve or the spinal cord may get compressed, causing pain, tingling, numbness, and/or weakness. This study was aimed at to access the anteroposterior and transverse diameter of the spinal canal.

Methods: All together 75 dried human vertebrae were gathered from Chitwan Medical College’s Department of Anatomy. Gender and ethnicity were unidentified. All damaged vertebras were excluded from the study. The diameters of the anteroposterior and transverse axes were measured. Photographs were taken, and the results were analyzed. The statistical study was carried out using Microsoft Excel 2019 and the results were assessed in terms of frequency and distribution.

Results: Among 75 dry vertebras were studied, the anterioposterior and transverse diameter of the cervical vertebra was between 9.77mm to 14.16mm and 16.35mm to 24.63mm respectively. In thoracic region, the anterioposterior diameter was between 11.82 mm to 15.53 mm and the transverse diameter ranged between 13.61mm to 18.96 mm. In lumbar region, the anterioposterior and transverse diameter was between 11.82 mm to 15.53mm and 13.61mm to 18.96 mm respectively.

Conclusions: We believe spinal canal has different anterioposterior and transverse diameter at cervical, thoracic and lumbar region. The findings may be help.
